`Application filed October 10. 1907. Serial No. 396,759.

y' T o all 'whom it may concern: t v Be itknown that I, WiLLiAM P.Leonie, af citizen of the United States, residing .at Canton, in thecounty of Stark and State of 5 Ohio, have invented a new and useful Improvement in Siphons, of which the following 1s a specification.

This invention relates particularly' to starting devices for siplionswhich act by exhausting the air from the siphon, and is intended as animprovement on the siphoii shown in Patent No. 773,511 granted toinyself and H. I). Minnick, on October 25; 1904. The present-inventionis, provided with improved means for exhausting the air, a piston andcylinder being used' instead of the collapsible bulb shown in saidpatent.

Other changes and improvements will appear from the followingdescription and t -drawings In the drawings-Figure 1 is a centrallongitudinal section'of the device, in one position. Fig. 2 is a similarview. in another position. Fig.A 3 is a view showing the practical useof the siphon. Fig. 4 isa detail .of a small tube used with small neckedbottles.

Referring s )eeifieally to the drawings, A indicates the liquidreceiving and air pumpv chamber in the' siphon; B the tube leading-thereto from the barrel or other liquid containing vessel; D an outlettube from said chamber; and Y the bottle or liquid receiving vessel. Thechamber A hasv at the top an inlet tube a2, an extension ol the cap c.,and connected to the tube B, and movable up and down in the tube a2 is atube valve J rovided with holes j inthe side and a disk y at the lowerend connected to the upper end of a cono shaped spiral spring K by means"of a lug i f- The lower vcap c of the cylinder A is provided with adepending tubular extension a,4 and a slight inner extension aiprojecting upwardly.' The extension af has a boss ai near its lower end,through which the thumb screw li is threaded.

wanna@ cylinder A is a piston o wie packing making a snug iit to thecylinder.' Attached tothe piston and evtending downwardly through thetube (13 is a tube c provided witli a flange c2 at its lowerv end, anumber of small openings c in its side near the base of the pisten,"anda shallow circumferential groovec4 in which the point of theSpecicationof Letters Patent.

screw L may be engaged. A vwasher c extends arou'nd the tube c atthe'basc of the piston and is heldin a groove lormcd in the underside'ofthe piston and seats against the extension ci 4on the lower cap of thecylinder. Y

The outlet tube D is slidably mounted within. the tube c and at the topit has a washerd which seats in a depression in the top of thepiston.'Outlet openings d are formed in the sides olsaid tube near the topthereof and normally open into the cylinder above the piston. At thelower end tue tube D has a cross piece E, adapted. to rest on the top ofthe bottle, and also has an extension tube D2 which screws into the endof said tube D.. This allows extension. tubes of various sizes to beused to accommodate the size of the vbottle neck. Thus, 1n Fig. 4, a

smaller tube illustrated, having a thread.

ed head to screw into the main tube. The cross piece E has elastictubing E over its arms to cushion the pressure on the neck el' thebottle. Also a spring catch G is attached to the middle portionolthe'cross piece and is adapted to engage over the flange c2 at the lowerend of the tube c, and a spring I" is ycoiled around the tube, betweenthe flange c2 and the cross piece.

The operationfis as follows:

The `endv of "a the hose B having been immersed in the liquid in theusual manner, the outlet tube D2 is thrust into the neck oi the bottleor other receptai'fle to be 'iilled, with thefcross piece E resting onmouth of saine and held firmly in position with the fingers of one hand.the other hand the cylinder or bodyY ol' the device is grasped and adownward pressure exerted ori-saine. This forces the tubeI) upwards,allowing the openings d to rise abovetiie top of piston, shown in F ig.1.

In Ithis position the coils of the spring F are contracted betweenthespider E and the flange c2. By continuing the pressure the tube c isforced upward, causing the piston (l to travel toward the upper end of-chai'nber A. The upward movement ol the piston causes a correspondingupward movement of the tube J through the medium of the spring K,bringing the openings in the said. tube J within the inclosing tube aff,the flange j bearing against the end of said tube. It is obvious thatthe air within the chamber Aeannot escape through the inlet tube a2, butmust pass out through the outlet tube D.

' tween t `pass out through sem@- r jsiehe" 'the' end. of its stroke thepiston is now retu ned to its originel position b v in upward pessi 'fon the cheinber. 'l Pi brings the wosner (l to its seat on the piston,elosing the openings d of tube D, end the piston continues its downwardtrnvel it forms partiel voeuuni in the upper end oi chamber wliiehcauses the tube J to be drawn downward against the decreasing resistnneeoi the spring L' bringing the open ings into n position to sillon' thenir in hose B to enter the clnnnber. ln order to avoid e compression ofnir below the piston the o enings ol which al of the position,
